Relax... Your mouth does not have the vasculature that would allow you to bleed out. By this time some healing should have formed but it would still be a raw wound. The best thing you should do is press gauze on the wound, as well as put some alcohol, just to keep out infection. Just see your doctor in the morning.
Your mouth if anything should be fine.
Right away. If you wait to long to rinse it out it could affect your skin or eyes.
